Hopping into 0.9

Hopping into 0.9 – Happy holidays guys!

Highlights

• Added new vehicle – Ibishu Hopper (more mod parts and variants coming in the next update)
• Improved tires and suspension for some cars (more coming)
• Added D-Series Crew Cab
• Added vehicle damage save/load
• Significant physics core optimizations (more than 30% faster) and improvements (see here for more details)
• Friction improvements
• Improved controller mapping system

Physics

• Physics core is more than 30% faster
• Improved stability of heavy object collisions (carrying heavy rocks case)
• Improved inter-vehicle collisions, anti-sticking works now for both front and back triangle faces. Adjustments might be needed for vehicle mods with misplaced nodes
• Improved accuracy of friction
• Added slidingFrictionCoef node property that acts like a multiplier only on the sliding friction of a node
• Added “stribeckExponent” and “stribeckVelMult” to node properties. It allows finer control of the sliding friction curve
• Improved accuracy of static collisions
• Static collision subsystem filters out degenerate (zero area) triangles. This fixes static collision clipping problems with collision meshes containing degenerate triangles
• Fixed instability with high lift coefficients in water
• Increased accuracy of wheel/rotator angular velocity calculations, they are accurate now even for “heavy” use cases that require high precision
• Rewrote mud/sand subsystem to use the same information as aerodynamics (in a non-newtonian fluid medium). It is more accurate now, but groundmodels will need to be adjusted
• Added “shearStrength” groundmodel coefficient. It defines the force (per area) that needs to be applied for the ground to start yielding
• Improved aerodynamic lift and drag curves
• Added airfoil lift curve approximation to triangle’ aerodynamics simulation (using lift and stallAngle triangle properties)
• Added “stallAngle” property to triangles. It defines (in radians) the angle where the lift will begin to stall
• Bananabench works again, it tests now up to 20 vehicles

Tire Physics

Node friction load sensitivity (WIP-Not all tires yet):

• Load sensitivity node properties are “noLoadCoef”, “fullLoadCoef” and “loadSensitivitySlope”
• Tire’s overall grip is reduced with increased load
• Lightly loaded tires have comparably more traction. This means less inside wheel spin with throttle in corners.
• The cars behavior and balance at the limit is more progressive, cars do not “tank slap” as much when trying to recover from a slide
• Cars can brake/accelerate with some 5-10% more force than they corner, because the wheelbase is longer than track, weight transfer reduces grip less in the longitudinal direction.
• Camber affects maximum grip in a more accurate way, because loading the outside tire nodes excessively, reduces grip due to load sensitivity.
• Vehicles, especially tall ones, are less likely to roll after hitting curbs or off camber situations, because the extreme camber reduces the grip through load sensitivity on the outside tire nodes.

Rolling resistance reduction

• Rolling resistance reduced another 10-30% by improving the node to ground collision code
• Increased aero drag to compensate for reduced rolling resistance

Tire “softness” friction property

• Nodes have a new “softnessCoef” property, which changes the rubber’s hysteretic behavior. This allows them to be more sticky in transient situations. When used in wheels, this improves steering response and makes the tire less likely to be shocked loose from the road by sudden input or a bump etc. It can also reduce loss of grip at high speeds (250+km/h) to a basically negligible amount.

Tire “treadCoef” + ground model “roughness” friction properties

• Tires have a tread coefficient that represents how well treaded the tire is (Slick = 0, mud tire = 1) we multiply this against a roughness coefficient in each ground type (mud has a high roughness, asphalt has very little) this means that a mud tire now works well in mud but mediocre on pavement, a slick works well on pavement but horribly on mud. Similar for other ground models.
• Choosing the correct tire for the surface is more important now, as off road tires will perform well off road but not so much on asphalt, and slicks will be great on asphalt but practically useless in mud.

Gameplay

(Middle-Click to use ‘fixed’ node grab)

Artificial Intelligence

Places target along planned path at a distance from the vehicle proportional to the vehicle’s speed.

• Bug fixes to the AI random pathfinder.
• Merge overlapping edges (forming triangles) of AI roads (navigation map) in map.lua.
